CD3 [PC3/188A]
Description CD3 is a protein complex and T cell co-receptor that is involved in activating both the cytotoxic T cell and T helper cells. It is composed of four distinct chains CD3γ, CD3δ, and two CD3ε chains in mammals. These chains associate with the T-cell receptor (TCR) and the CD3-zeta (ζ-chain) to generate activation signal in T lymphocytes. The TCR, CD3-zeta, and the other CD3 molecules together constitute the TCR complex. CD3 is initially expressed in the cytoplasm of pro-thymocytes, the stem cells from which T-cells arise in the thymus. The pro-thymocytes differentiate into common thymocytes, and then into medullary thymocytes, and it is at this latter stage that CD3 antigen begins to migrate to the cell membrane. The antigen is highly specific marker for T cells, remains present in almost all T-cell lymphomas and leukaemias, and can therefore be used to distinguish them from superficially similar B-cell and myeloid neoplasms. This monoclonal antibody recognizes the epsilon-chain of CD3.

CD31 (PECAM-1) [JC70A]
Description CD31, also known as PECAM-1, is a 130 kDa integral membrane glycoprotein found on the surface of endothelial cells, platelets and some hematopoietic cells. The antibody labels endothelial cells of arteries, arterioles, venules, veins, and non-sinusoidal capillaries in various tissues. CD31 is the most sensitive and specific endothelial cell marker. It is useful for detection of tumors with endothelial origin. In addition, CD31 has been used to identify vascular invasion of tumors, and assessment of angiogenesis which is a prognostic marker for many types of cancer.

CD38 [AT1]
Description CD38, also called ADP-ribosyl cyclase, is a druggable ectoenzyme that uses nicotinamide adenine dinucleotide (NAD) as a substrate to generate second messengers. In particular, it synthesizes cyclic ADP-ribose, a second messenger for glucose-induced insulin secretion. CD38 also has cADPR hydrolase activity. It is preferentially expressed at both early and late stages of B- and T-cell maturation. In normal lymph nodes and tonsils, the antigen is detected mainly on B cells in germinal centers and plasma cells. An antibody to CD38 is helpful in the identification of plasma cells and tumors with plasmablastic differentiation. A prognostic value of CD38 in B-cell chronic lymphocytic leukemia (CLL) has been reported. Expression of CD38 is linked to unmutated IgVH genes and a worse prognosis. CD38 is involved in the generation of adenosine, which is implicated in tumor immune evasion. CD38 mRNA expression in metastatic castration-resistant prostate cancer (mCRPC) was most significantly associa Host Mouse Application Flow cytometry (FC), Immunofluorescence (IF), Immunohistochemistry (IHC), Immunoprecipitation (IP), Western Blot (WB) Reactivity Human -

CD4 [MT310]
Description CD4 is a glycoprotein found on the surface of immune cells such as T helper cells, monocytes, macrophages and dendritic cells. It is a co-receptor that assists the T-cell receptor (TCR) with an antigen-presenting cell and also interacts directly with MHC class Ⅱ molecules on the surface of the antigen-presenting cells using its extracellular domain. In lymphatic tissues, the CD4+ T-cells are seen in large numbers in the parafollicular zone, while scattered cells are found in the germinal centres and mantle zone. CD4 is also demonstrated in hepatic sinusoidal cells, monocytes and monocytes-derived cells but not expressed on B-cells and immature thymocytes. Precursor T-lymphoblastic lymphomas are therefore variable in their expression of CD4. Most mature T-cell lymphomas are CD4 positive with the exception of aggressive NK-cell leukemia and extranodal NK/T-cell lymphoma. CD4 plays an important role in the classification of lymphocytes in inflammatory lesions and malignant lymphomas.

CD42a [A9]
Description The CD42a antibody recognizes a 17 to 22-kilodalton (kDa) single-chain, platelet membrane glycoprotein, also known as gpIX that forms a noncovalent complex with gpIb and gpV. Glycoprotein Ib consists of an α–chain disulfide-linked to a β chain. Glycoproteins Ibα (140 to 145 kDa), Ibβ (24 to 25 kDa), and V (82 to 86 kDa) have been designated as CD42b, CD42c and CD42d respectively. CD42a has been reported to react with both gpIX and the gpIb-IX-V complex.

CD42b [42C01]
Description The CD42b glycoprotein, also known as GPIb, is a co-factor of ristocetin-induced aggregation and is involved in the binding of platelets to blood vessel walls. The CD42b antigen is expressed on platelets and on megakaryocytes in bone marrow. The absence of CD42b antigen on platelets may indicate Bernard-Soulier disease. CD42b is a platelet activation marker involved in the process of coagulation as an aggregating factor. It interacts with extracellular matrix as well as with adhesion molecules. Its expression and activation seems to be regulated by VEGF and PDGF.
